“…The information on these hazard zones is provided in the Table 5 that follows and it provides helpful details on the various flood risk levels in the research area. Implementing this classification enables stakeholders and decision-makers to allocate resources and priorities mitigation measures to locations with greater flood danger levels improving overall disaster management and preparedness efforts [35][36][37]. A computed velocity pattern during a flood event with a 100-year recurrence interval is shown in Figs.…”

Floods stand out as one of the most devastating environmental threats worldwide resulting in the tragic loss of human lives and significant damage to our essential infrastructure. This study focuses on creating floodplain maps for the two important reaches of Swat River in the Khyber Pakhtunkhwa Province of Pakistan, namely, Kalam–Khwazakhela and Khwazakhela–Chakdara reaches. The Advanced Land Observing Satellite Phased Array Type L-band Synthetic Aperture Radar (ALOS PALSAR) 12.5 m Digital Elevation Model (DEM) data has been used for this purpose. Furthermore, the sensitivity of the flood model was assessed for the Flood 2022 event, considering simulated flood depth, extent, and velocity in relation to various terrains derived from the 12.5-m ALOS PALSAR data. To estimate extreme flows for different return periods (2, 5, 10, 25, 50, and 100 years), the Log Normal (LN), Log Pearson III (LP3), and Generalized Extreme Value (GEV) distributions were employed for the frequency analysis. The GEV distribution turned out to be the best fit for modeling the Swat River for both the Chakdara and Khwazakhela gauge stations. To predict flood levels for the peak floods identified through frequency analysis and for the specific return periods the Hydrologic Engineering Center's River Analysis System (HEC-RAS) 2D simulations were performed. Subsequently the outcomes of this model were used to create floodplain maps using Geographic Information System Professional (ArcGIS Pro) software customized for various return periods. The analysis revealed a linear increase in flood inundation area with longer return periods. The floodplain maps developed hold significant importance for the governing authorities of the Swat region. These maps serve as essential tools for implementing proactive measures against potential infrastructure damage, thereby protecting against economic losses and enhancing public safety. This research effectively combines hydrological modeling and geospatial technology offering practical solutions for managing flood risks. It serves as a valuable guide for making well-informed decisions and promoting sustainable development in flood-prone areas.

“…Done et al (2018) find that new construction under stronger building codes can also reduce losses from hurricanes. However, evidence exists, at least in North Carolina, that substantial new housing construction is occurring in flood zones, so that the net direction of risk is unclear (Hino et al, 2024). Kim (2020) finds that structural elevation and green infrastructure positively associate with the value of nearby housing in Miami-Dade County and New York City during 2009-2018.…”

With near unanimity, climate scientists project natural disasters to increase in frequency, severity, and geographic scope over the next century. We survey academic literature at the intersection of these climate risks and real estate. Our review of physical risks includes price, loan performance, and migratory effects stemming from flooding, wildfires, and sea level rise. We review transition risks, including energy use and decarbonization, as they relate to real estate. Where possible, we explain how these topics may intersect with housing affordability, especially in historically disadvantaged communities. We conclude by highlighting critical areas for future research.
